Abstract: 2086.112 PROCESS FOR EFFECTING CHEMICAL REACTIONS                 ABSTRACT OF THE DISCLOSURE   A process for effecting chemical reactions, including wet oxidation reactions, in a deep well or down-hole reactor preferably providing a crosscurrent flow in a nested tube configuration wherein the influent fluid is in heat transfer relation with the effluent fluid. The disclosed process includes flowing an influent fluid including the reactants downwardly through a downcomer pipe which extends below ground in a subterranean opening or well casing forming a hydrostatic column of fluid, which defines a predetermined pressure, with the reactants at a temperature sufficient to initiate and maintain the desired chemical reaction. The method then includes flowing the effluent fluid upwardly through an upcomer pipe to ground level, preferably in heat transfer relation with the downflowing influent fluid. The method of this invention includes boiling the effluent fluid in the upcomer pipe, thereby reducing the hydrostatic fluid pressure in the upcomer and increasing the mass flow rate. The boiling of the effluent in the upcomer pipe may be initiated periodically at predetermined timed intervals to reduce pump pressure and increase the mass flow rate through the apparatus or the boiling of the effluent may be maintained to substantially eliminate pump pressure following initiation of an exothermic reaction in the reaction zone defined at the lower extent of a deep well reaction apparatus.

Granted: 1992-04-28
Abstract: ABSTRACT            Heat exchanging or circulation apparatus comprising a system of conduits connected to an inlet and an outlet for circulating water or other practically incompress-ible liquid through the system, heat being transferred through the conduit walls, circulation in said apparatus being periodically shut off, whereupon continued heat transfer through the conduit walls causes freezing of the liquid to ice in the conduits. The two first portions of said system are relatively heat-insulated or shielded from flowing cold air to obtain delayed freezing of water in said portions in relation to the freezing of the liquid to ice in uninsulated second portions of said system located between said first two portions so that ice growing in said second portions towards the ends thereof being in communication with said two first portions will result in an increased pressure on the unfrozen liquid in said insulated portions of the system, said increased water pressure being relieved by having said two first portions each connected through insulated branch conduits with a closed insulated pressure relief or absorbing means so as to avoid rupture of the conduits in any portion of the system.

Granted: 1992-07-21
Abstract: METHOD AND APPARATUS FOR A HEATING FUEL #20.089 ABSTRACT OF THE DISCLOSURE       A device  for transporting and preheating fuel which is susceptible to cold temperatures comprises a pump which has an electromagnetic coil which is supplied with current to move a plunger for pumping the fuel so as to transport it.  The plunger is  returned  for  example,  by  a  return  spring  and  the electromagnetic coil is set out so that a maximum portion of the coil heats a fuel as it is passed through a pumping space.  In accordance with the method of the invention, the coil has its own current supply control which advantageously may be set to supply a heating current which is in excess of that required for moving the plunger.  A return spring set for returning the plunger may also be made stronger than necessary to effect return and the timing of the operation of the coil for moving the plunger may be set to be longer than necessary in order to keep the coil at a higher operating temperature and thus transform more heat to the fuel.  The pump itself is designed so that the pumping space is in  substantially  direct  contact  with  the  housing  for  the electromagnetic coil so a maximum amount of temperature may be imparted.  Casing for the pump may be a heat insulating casing or it may be arranged in an outer housing which is spaced from its exterior and the entire heating of the pump during its operation transfer to the fuel which is passed in between the pump housing and an outer housing.
